PARALLEL ADJUSTABLE SWING-JOINT.

SPECIFICATION forming part of Letters Patent N 0. 679,222, dated July 23, 1901. Application filed March 18, 1901. Serial No. 51,693. (No model.) 7

To all whom it may concern.-

Be it known that I, EDWARD J. FILIATRAULT, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Parallel Adjustable Swing-Joints and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in joints for conduits, and more particularly to the swinging or pivoted type adapted for use in connection with electric conduits.

One object of my invention is to provide a swinging joint which may assume almost any angle and be locked at such angle.

Another object of my invention is the provision of a joint of the type described which shall have a clear wholly'unobstructed central passage.

A further object of my invention is the provision of a pivoted joint for electric conduits which may be locked at any desired angle, said locking means being controlled bya key carried thereby.

With these objectsin view it consists of a bifurcated member adapted to receive and retain at any desired angle the bifurcated end of an opposing member.

It also has other objects in view; and it consists of certain other novel constructions,combinations, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a cond nit-joint embodying the features of my invention. Fig. 2 is a longitudinal section of the parts shown in Fig. 1 on line m 00 thereof, except that the thumb nuts and screws have not been cut away to more clearly illustrate the direction of the threads. Fig.3 is a fragmentary view of a slightly-modified form of locking means employed in connection with my improved joint. Fig. 4 is a similar view to Fig. 2 of a slight modification, and Fig. 5 is a perspective view of the key to be applied in locking the form of joint illustrated in Fig. 4.

Referring to the drawings by numerals, 1 indicates a ferrule applied to the ends of the two parts forming one-half of a joint. These two parts are formed separate and brazed together or may be formed in one and constitute when united one of the bifurcated parts 2 2. Each of the arms, as 3 3, of each bifurcated member 2 is of concavo-convex form,and the arms 3 of one of the parts 2 are adapted to fit within and their convex faces rest snugly against the concave faces of the opposing arms 3 of the other member 2. The parts 2 are bifurcated, and a slot, as 4-, isleft between them, so that when the members are moved to different angles a clear central passage will be provided. The concavo convex parts '3 3 are of disk shape, as seen in Fig. 1, and are perforated in the center thereof, as at 5, the perforations of one arm 3 of one part 2 registering with the perforation of the opposing part, and a threaded bolt is passed therethrough, as at 6 6, and nuts, as 7 '7, may be threaded thereon. The nuts 7 may either be circular and milled to serve as a thumb-nut, in which instance the thread of both of bolts 6 is right hand, or the nuts may be polygonal, in which instance I prefer to form the bolts with oppositely running threads, one to the right and the other to the left hand, whereby when both nuts are turned in one direction the joint will be firmly locked, and when they are both turned in an opposite direction the joint will be free to be moved to any angle desired. It is obvious that when milled nuts are used two left-hand-threaded bolts may be used with the same result as if two right-hand bolts were being used, and when employing the said milled nuts I intend that the locking operation and the unlocking of the joint shall be performed by hand without auxiliary means, the efiect of tightening and loosening the nuts being the same as above described.

When using the polygonal nuts, I prefer to provide a key or wrench, as S, which is formed with bifurcated ends adapted to engage each of the nuts 7, both of said nuts being operated upon at the same time and the body of the key or wrench extending across the joint. When in this position, the key or wrench may be pressed longitudinally of the joint and to one end of slot 4, thereby locking said joint against movement, or said key may bepressed Threads, as 9 9, may be provided at the opposite ends of the joint, whereby the same may be attached to a conduit, or any other desirable securing means may be employed.

In the slight modification shown in Fig. 3

' I have shown a very rapid means for locking and unlocking my improved joint, the same 5 V cated members, the bifurcated portion of one being constituted of the usual bifurcated members 3 3 with the bolt 6; but in this instance I prefer to penetrate the bolt with an elongated eye, as 11, at the outer end thereof, through which eye is passed a segment of any preferred form, as 10, which segment is provided with a handle or other operating means, as 12, whereby by removing the segment the joint will be loose to move to different angles, and when the segment is inserted to the proper distance the joint will be locked against movement Although I have described specifically my invention in detail, yet Ido not wish to be understood as limiting myself to the exact form specified, but shall feel at liberty to deviate from the exact size, shape, and minor details of construction within the spirit and scope of iny invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A conduit-joint comprising interlocking bifurcated members, means for locking said members at any desired angle with relation to each other, and means for operating said looking means, substantially as described.

2. A conduit-joint comprising two bifurcated members, the bifurcation of one member fitting snugly within the bifurcation of the opposite member, wherebya clear central passage will be provided, and means for locking scribed.

said bifurcated members together, substan tially as described.

3. A conduit-joint comprising two bifurcated members, the walls of said bifurcated portions being concavo-convex, and the convex faces of the bifurcated portions of one member being adapted to fit snugly the concave faces of the bifurcated portions of the 1 opposing member,whereby a clear central passage will be provided, and means for locking said parts at any desired angle, substantially as described.

t. A conduit-joint comprising two bifurcated members, the bifurcated portions of one member being adapted to fit within the bifurcated portions of the' opposing member, and hand-operated means for locking said parts together, substantially as described.

5. A conduit-joint comprising two bifurmember being formed with an aperture adapted to register with a like aperture in the opposing bifurcated portion, a bolt passed through said registering apertures,and means carried by the outer end of said bolt for looking the parts together, substantially as de- 6. A conduit-joint comprising two bifur cated members, the bifurcated portions of one member being adapted to fit within the bifurcated portions of the opposing member, bolts 1 passed through said bifurcated portions, nuts carried thereby and means for revolving said nuts, whereby said joint may be locked with the members at any desired angle with relation to each other, substantially as described. 7. A conduit-joint comprising members pivotally secured together,bolts forming said pivots, nuts carried by said bo1ts,the thread upon said bolts running in opposite directions, and akey adapted to engage both bolts at the same time, whereby a movement of the same in one direction will lock the joint and a movement in the opposite direction will unlock the same, substantially as described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
